Yes we can do a soil sample. We need about two cups of dirt to send in for the Sample. You should take dirt from four different spots in the area that you want tested, put it in something to mix it up and then bring us about two cups of dirt from that sample. List what area it is from Like Lawn, Garden, Food Plot, Flower Bed, New Lawn Seeding, etc. It take about one to two weeks to get it back and it does cost to send it in.
